EARL WAYLAND KRIZAN A TTORIVE Y United States Patent 3,275,006 SMOKING PIPE Earl Wayland Krizan, 5317 Wooten Drive, Fort Worth, Tex. Filed Sept. 3, 1964, Ser. No. 394,209 4 Claims. (Cl. 131-183) This invention relates to smoking pipes and has reference to a pipe bowl construction and preloaded tobacco cartridges therefor.

An object of the invention is to provide a pipe and tobacco cartridge wherein the remaining unconsumed end of the cartridge may be easily and readily removed from the pipe bowl.

Another object is to provide a tobacco cartridge for a pipe wherein the cartridge includes a non-combustible strip along the side thereof to further facilitate the removal of the cartridge.

Another object is to provide, in combination with the foregoing objects, a hinged door in the bowl whereby the remnant of the cartridge may be easily reached for removal of the residue.

A further object is to provide a tapered cartridge receiver within the pipe bowl, together with a manual lift therein for raising the remains of the cartridge prior to removing the same from the bowl.

Generally, the invention contemplates a pipe and tobacco cartridge wherein the cartridge is spaced from the bowl for cool leisurely smoking, wherein the tobacco will burn longer between puffs on the pipe, and wherein less reaming and scraping of the bowl is required. Additionally, the construction of the bowl and cartridge support is such that any accumulated saliva in the pipe stem and bowl is less likely to come in contact with the tobacco.

These and other objects of the invention will become apparent from the following description and the accompanying drawing, wherein:

FIGURE 1 is a longitudinal vertical sectional view of smoking pipe including the present invention.

FIGURE 2 is an enlarged perspective view, shown partly in section, showing the cartridge support in the pipe bowl.

FIGURE 3 is a fragmentary perspective view of a tobacco cartridge in accordance with the invention.

FIGURE 4 is a fragmentary top plan view of the cartridge holding and lifting mechanism.

FIGURE 5 is -a vertical sectional view of the bowl and a portion of the cartridge as illustrated in FIGURE 1, but showing the cartridge lifting mechanism in its raised position and the bowl door in its open position.

The pipe shown in the drawing includes a bowl 11, stem 12 and mouthpiece 13, all in the usual manner. Within the bowl 11, and secured to the forward wall thereof by a vertical plate 14, there is a tapered ring 15 for receiving the lower end of a tobacco cartridge, generally indicated by the numeral 16. The ring 15 is near the bottom of the 'bowl, and a perforated disc 17 is slidably received therein and provides a locator for the lower end of the cartridge. As will become apparent in the description of operation to follow, the disc 17 has to do with lifting the cartridge residue. On the forward edge of the disc 17 there is a vertical lift arm 18 in a' corresponding groove 19 in the bowl 11. The lower portion of the vertical plate 14 and the side of the ring 15 adjacent thereto are slotted, at 20, to accommodate the lower end of the lift arm 18 where it connects the disc 17. The upper end of the arm 18 is bent outwardly over the rim of the bowl 11 to provide a lift tab 21. Transversely of the groove 19, and also recessed in the bowl 11, there is a generally 3,275,006 Patented Sept. 27, 1966 ice U-shaped guide 22 which slidably engages the outer surface and the edges of the arm 18. As best shown in FIGURE 2, the arm 18 is shouldered on each side at a, and which shoulders contact the guide 22 when the arm is in its raised position.

As best shown in FIGURES 1 and 5, the rear portion of the bowl 11 includes a door 23 which is hinged to the bowl, by hinges 24, just above the pipe stem 12. The lower end of the door 23 and the last referred to portion of the bowl 11 have magnets 25 therein, the polarity of which is arranged to normally maintain the door in its closed position. Spring loaded hinges, not shown, may be used but would have the effect of urging the door 23 to its closed position at all times.

Referring now to the cartridge 16, the same is comprised of a combustible cylindrical wrapper 26, such as cigarette paper, and is uniformly packed with cut pipe tobacco 27. The cartridge 16 shown includes a filter 28 in its lower end. Preferably, the wrapper 26 is at least two layers thick and includes a strip 29 of noncombustible material, such as metal foil, along one side and which strip of material is herein referred to as a pull strip 29. As shown in the drawing, the strip 29 is embedded be tween the layers of the wrapper 26 and the location of the strip is indicated by vertically aligned marks 30 on the outer wrapper surface. The marks 30 also indicate the length of the cartridge 16 received in the tapered ring 15.

In operation, the cartridge 16 is inserted in the bowl 11 of the pipe 10 until the lower end of the cartridge seats in the receiving ring 15 which is in its lowermost position at this time. By opening the door 23 the user may observe, by means of the marks 30, how much of the cartridge 16 is received within the ring 15. The door 23 is then closed and the upper end of the cartridge is lighted in the usual manner. By reason of the cartridge being spaced from the bowl 11, a cool smoke is assured and the burning of the tobacco is enhanced so that longer periods of time lapse between puffs to provide a leisurely smoke. Because the disc 17 is spaced from the bottom of the bowl little or no saliva will come in contact with the tobacco 27. After the cartridge has been consumed the residue is removed by lifting the tab 21 and raising the disc 17. The door 23 is then opened, and 'by means of the noncombustible strip 29 the residue of the cartridge is removed from the bowl.

The invention is not limited to the exemplary construction herein shown and described, but may be made in various ways within the scope of the appended claims. What is claimed is:

1. In a smoking pipe including a bowl, a ring within said bowl around the inner wall thereof, a perforated disc transversely received in said ring, a lift arm connected with an edge of the disc and extending upwardly to the rim of said bowl, means slidably receiving and guiding said arm and connected disc, and a cylindrical tobacco cartridge received in said ring above said disc, said ring being tapered downwardly and inwardly and the peripheral portion of the lower end of said cylindrical cartridge being dimensioned to engage the innermost portion of said tapered ring.

2. In a smoking pipe as defined in claim 1, the construction including a door in said bowl and hinges connecting said door with said bowl.

3. In a smoking pipe as defined in claim 1, the construction including a pull strip of non-combustible material secured along one side of said cartridge.

4. In a smoking pipe as defined in claim 2, and including magnets in said door and said bowl, said magnets being opposite each other when said door is closed, the

3 1 polarity of said magnets being arranged to normally hold 2,937,648 said door in its closed position. 3,117,579
